Re(l)ality: The View From Nowhere vs. The View From Everywhere — •Nicola Bamonti — nicola.bamonti@sns.it

Using the fiber bundle framework, this work investigates the conceptual and mathematical foundations of reference frames in General Relativity by contrasting two paradigms. 'The View from Nowhere' interprets frame representations as perspectives on an invariant equivalence class, while 'the View from Everywhere' posits each frame representation as constituting reality itself. This conception of reality is termed 'Relality'. The paper critically examines the philosophical and practical implications of these views, with a focus on reconciling theory with experimental practice. Central to the discussion is the challenge of providing a perspicuous characterisation of ontology. The View from Nowhere aligns with the so-called 'sophisticated approach on symmetries' and it complicates the empirical grounding of theoretical constructs. In contrast, the View from Everywhere offers a relational ontology that avoids the abstraction of equivalence classes. The paper may establish multiple points of contact with discussions on the ontology of Relational Quantum Mechanics. In particular frameworks like the View from Everywhere and the Relality definition can offer valuable insights in that context
